The minimally invasive surgery for pancreatic achalasia is POEM surgery, i.e., transoral endoscopic esophageal sphincterotomy, which is a minimally invasive surgery with less damage to the patient and faster recovery, and is a lower-risk clinical treatment for pancreatic achalasia. Pancreatic achalasia is a disease of esophageal neuromuscular dysfunction, which is characterized by high pressure in the lower esophageal sphincter and weakened swallowing reflexes, resulting in clinical symptoms such as dysphagia and reflux. The main treatment modalities are surgical incision of the lower esophageal sphincter to improve symptoms, including endoscopic balloon dilatation, stent implantation, and the latest minimally invasive surgery, POEM. The main procedure of minimally invasive surgery for pancreatic achalasia is to cut the mucous membrane layer at the lower esophageal sphincter with a knife, create a tunnel opening from 30cm to 50cm away from the incisors, and then use a knife to cut off the esophageal circular muscle, and then finally clamp the tunnel opening closed. The whole procedure is painless with general anesthesia, and the clinical symptoms such as dysphagia are significantly improved and the wound recovers quickly after the operation. The traditional endoscopic cardia surgery is very traumatic and the patients have a long recovery time. The new minimally invasive surgery will replace the traditional surgery, but the minimally invasive surgery is difficult to operate and has high requirements for equipment and instruments. For patients with pancreatic achalasia, the surgical method should be judged by considering their family background, individual situation, and the medical level of the hospital.
